FMS is it working on my server ?

Hello,

I instaled FMS 3.5, developper edition on linux (Gentoo).
I created a user and group "fms" to start the server.

Server seems working. In fact, with admin cosole (the html page), i can see instances of application (subdirectories of "application" directory).
But when i try to connect to the server with Flash pro (with the code at the bottom), connection fail (NetConnection.Connect.Failed).

I created a directory "tt" as subdirectory of "application" with the owner fms:fms.

Do you have an idea ?
What others tests can i do ?

Thanks.
